t Be it known that we, FREDEincn F. BionEN and JAMns C. BronEN, citizens oi' the United States, residing at Nenn-rk, in thel county ot' 5 Essex and State ot' New Jersey, haveinrented pose; andfit consist-sin the arrangement and;

combination of parts, substantially as Will'be 2o hereinafter set forth, and embodied in the claims. 1

Referi'hig to the accompanying,` drawings, in which similar letters of reference indicate like.

Fig. 6 is a section' 35 cfa revolving brush, and illustrates more especially the arrangement of the bristles therein. Fig. 7 illustrates one end ol' said rerolving brush, showing' its adjust-able relation to 'i earings. ,i i 4o 1 carrying out oni" invention we construct a suitable carriage or truck ot'suliicient capacity and strength to carry a small engine or other motor and the mechanism hereinafter described, anduponv the same said truck we 45 erect a traine-work, b, which carries certain traveling tables or belts, by which the dirt is conveyed from the brushes and' thrown into a cart stationed alongside ot the sweeping-nia-A chine. 5o O n the posteriorendot' the 'machine arcsecured adjustable arms a, pivotedto the "cari riage at one end thereof and-:supportedbysuitable wheelsor casters, Z/f, arranged'atfthe other so that the last said 4end may loehlraised` or lowered, the franieof the casters being pro- ,5 ,vided with slots bi, r'which engage', with bolts on the arms, as willybeapparent upon reference to Fig. 1.` Y z" The' arms'u carry' slotted bearings cf-for the revolvingbrush, jouriial-lioxes c,.sliding` in 6o saidUbeariDgS, and the journals of the said brush Working in said boxes. Suitable springsV are arranged,be11eathsaid journal-boxes to take'a 'portion of the Weight off the bristles, so that theV samewill not bear too hard upon565A the Yground and Wear away too rapidly. The brushes B are constructed and actuated as will be hereinafter particularly set forth.

Upon the bar b 'of thev frame, upon the truck, or upon 4any suitable portion of the 7o truck, is pivote-d an inclined plane, 1, extending from 'a point in close proximity tothe ground, where .it receives the dirt thrown by the rapid revolution of the brush B. The said inclined plane is provided with suitable roll- 75 ers, e, which are preferably vadjust-ably secured tothe same. The inclined plane is further provided' with adjustable bearing-'arinsj`, in or on which pulleys g are journalecl.-V Said pulleys carry straps orbelts h, upon which 8o are' secured Scrapers fi, adapted to engage with the inclined plane and cause the dirt'lto be movedupward thereon, said inclined plane being` provided at the -sides with suitable guards, d', to prevent the dirt from prema- A85 iurely falling` therefrom.` v We arrange in the frame b the rolls k k', `the latter lying` beneath the inclined plane.

Upon said rolls we stretch a belt, Z,` provided `with lags m, which, combined, carry the dirt 9o to its highest elevation in the machine, as will be manifest. eneath the upper,extremityot' thehlstunentionml belt ism-ranged a trans versc belt, o, carried by suitable rolls or pul- 'lcys, wliiclrn'ork in journal-bearings p on the 95 frame?) b, one ot' saidrolls beingjournaled at or near/the extremity ol' arms yi', Fig. 2, which project from the sideol'the machine a sutlieient `distance to overlie the body otihe cart, which latter is intended iobeeoupled. to the truck, roo

Y' so that when said transverse belt is in operation the dirt which is received from the belt l 'villbe thrown or dumped into said cart;-

i Beneath thetruekAis arranged and secured f a suitable fran1e-work, C, which Tcarries. the

`be fore-mentioned. picking device.` Said pick-v ing de vice is composed of rollers 'provided with comparatively rigid or stiff metallic rods of sufficient strength to cause the stiff earth,

` I'o often-,to bei'ound in streetsftobe loosened up prior to' being swept by the brush. The frame upon which said picking-rolls workis adjustvable, as`clearly indicated in Fig. {1, so that the saine may be raised orlowered' to suit the na- 1.5` ture'of the work to be accomplished or to take up wear; Thepicking-rolls-are, preferably, di-

' .vided` into sections, as shown in Figs. 1 and 3,y

and arearran'ged in spring-bearings, so that the said 'rollsmay adjust themselves to the o'asual curvature of the street or other irregularities therein. Each one of said rolls is pro# videdwith pulleys, shoWn. -Theparts thus' described- -are actuated by the-pulleys and belt 3, 4, ande, actuates the rolls/or drums which carry th'e'.trans\ferse belt o. The-pulley w'uponl the shaft with the gearwheel communicates power, by means of the beltGy and'pulley 7, to the drum pul- 4o ley or pulleys k', which actuate the belt Z. The

' pulley u is arranged upon a shaft with and communicates 'power to the pulleys 8 and 9,

thelatter vbeing shown in outline in Fig. 1.

Said .pulleyS is connected to 'the pulley '10,

a'which causesthe brushBto revolve by means of the belt 11, whilel the pulley or pulleys'9 'communicate motion to the picking-rollsl2 Vand 13 by means ofthe belts 14 and`15.v

` The operation of the machine is as follows:

Y 5o Horses are attached to the truck in anyordinarymanner 'and draw the machine' over thel surface' to be cleaned. The engine causes the various mechanisms to revolve, and the picks loosen the dirt, as before stated, and bring it 5 5' toa state such as that when the brushes thereon, it will be readily and thoroughly swept upon the .incl-ined plane. The Scrapers 'i cause the dirt to pass' upward over the incline and to'fall upon the belt. Z,- provided with lags m,

l o-whichcontinues the upward progress of thedirt until 'it reaches'a'point above the transversely-moving belt o, 'upon 'which the-'said dirt is thrownf (a1 guard, 1 6, being stretched across-theiframe'to prevent thedirt from pass ing beyond pr'oper limits) and.' carried to and dumped into the cart.v 'It is intended that the said cart shall be' drivenfalcngside of and stacca".

make progress with the sweeping-machine'bef `ing coupled thereto 'by some ready method of v r 'L coupling; that when saidl cart is full that the 7 0;

same willbe uncoupled and driven away and a second brought to work in conjunction with the machine, and 'so on as the work requires.V

In forming the revolving brush we construct a bed, 20, Figs. 6 and 7, having wings 21 and 75 side disks, 22, and having bolt-passages 23, all 1' arranged in substantially the manner shown. The flanges, disks, and bed-proper form conjointly depressions, into which are arranged plates 27, adapted to' conform thereto. The

bristles 28, which are formed of any suitable material of sufficient strength and durability,

are laid across the depressions, and the plates, when they are brought to bear thereon, bend l" said bristles into the depressions. Bolts are then arranged to secure the plates, as shown,

the preferable method being to pass the bolts through bolt-passages and secure two plates at once, as clearly indicated. To make the brush B readily adjustable in the machine we prefer to make ythe journalsy detachable` therefrom, as illustrated by Fig. 7, in which 24 2l are bearing-plates bolted or otherwise secured to the side disks, 22 22, said plates having the journals 25 25 formed there' Aon or secured thereto. By simply unbolting the vdislvand plate, the brush may be quickly removed and be replaced by a new one.

. The several pulleys herein shown are prefierably connected by Ybolts formed of links roo hinged together as shown, each link having an aperture, 30,'Fig. 5, therein, adapted to engage with lugs 31 upon the pulleys. This arrangement prevents the belt from sliding, and is necessitated. by the uneven orirregular nature of the work to be performed.

- Having thus described our invention, we

Vdonot wish to be understood as limiting ourselves to they precise arrangement of partsherein set forth, as it is evident that very material changes can' be made in the device with'-v out departing from the spirit of the invention; i but v 'lVhat we claim is l 1. lIn combination. in a street-sweeping device, a brush, B, inclined plane d, Scrapers i, belt Z, and transversely-movable mechanism arranged tol receive the dirt from the said belt I, substantially as and for the purpose herein set fort-h.
